Solution Overview

Problem

Current automation systems lack an efficient method for sharing optimized operation data between local control devices, leading to suboptimal performance and increased time consumption in adapting control strategies across field devices.

Innovation Solution

A method and system where local control devices generate and share upload data containing optimized configuration modifications, with a central control device anonymizing and distributing this data to other local control devices based on similarity and past performance, enabling knowledge transfer and adaptive optimization without sensitive information sharing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If local control devices share operational data to improve field device performance, then productivity and optimization efficiency are improved, but security and privacy of sensitive information are compromised

Engineering Contradiction:
Improvefield device performanceVSAvoidinformation security
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the essential operational parameters and performance data from the uploaded information, separating them from sensitive proprietary information. The server processes and analyzes only the extracted operational data to generate optimization recommendations, while the original sensitive information remains local to each control device. This resolves the contradiction by enabling productivity improvement through data sharing while protecting security through selective extraction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The server acts as an intermediary that receives uploaded information from local control devices, processes the data to extract operational parameters, generates optimization recommendations, and returns them to the control devices. The server never stores or exposes the original sensitive information, serving only as a processing mediator. This enables collaborative optimization across multiple devices while maintaining information security through the intermediary's controlled processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If local control devices independently optimize their configurations through trial and error, then adaptability is improved, but time consumption and operational efficiency deteriorate

Engineering Contradiction:
Improveconfiguration adaptabilityVSAvoidoptimization time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements feedback loops where local control devices upload operational results and monitoring data to the server. The server analyzes this feedback from multiple sources, compares performance across different devices and configurations, and generates optimized recommendations based on collective learning. This feedback mechanism enables rapid adaptation by leveraging experiences from multiple devices simultaneously, dramatically reducing optimization time compared to independent trial-and-error approaches.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The server performs preliminary analysis of uploaded data from multiple control devices, pre-processing and comparing operational parameters before generating optimization recommendations. By preparing and analyzing data in advance from multiple sources, the system can provide ready-made optimized configurations that significantly reduce the time each individual device would otherwise need to spend on independent optimization trials.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If detailed operational data is shared across the network, then manufacturing precision and optimization accuracy are improved, but data transmission volume and processing complexity increase

Engineering Contradiction:
Improveoperational precisionVSAvoiddata processing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The server extracts only the essential operational parameters needed for optimization from the uploaded information, such as process variables, performance metrics, and operational states. By extracting only the necessary data elements rather than processing complete detailed datasets, the system maintains manufacturing precision while significantly reducing data transmission volumes and processing complexity. The extraction focuses on parameters that directly impact optimization decisions.

Inventive Principle:
Principle #2Taking out (Extraction)
